摘要:
A guided missile or projectile and associated guidance control are provided to control a path to a point of intersection with a potentially moving target. A new path is repetitively recomputed and acceleration orthogonal to the path is applied to minimize heading error and thereby to converge on the target. The gain of the control function is partly proportional to heading error, but the gain is reduced approaching the point of convergence. In this way, the guidance control is more responsive to actual variance of the true heading error and is less responsive to random error in sensing the target heading, which random error would otherwise increase in its contribution to corrective guidance movements approaching the point of intersection.
摘要(中):
提供导弹或射弹及相关引导控制以控制与潜在移动目标的交点的路径。 重复地重新计算新路径,并应用与路径正交的加速度,以最小化航向误差,从而收敛于目标。 控制功能的增益部分与航向误差成比例,但增益减小接近收敛点。 以这种方式,引导控制对真正方向误差的实际方差更有反应,并且对感测目标航向的随机误差的响应较小,随机误差对其接近交点的修正引导运动的贡献将增加。
